Fixed memory exception on cellJpgDec & cellGifDec

* Added support for CELL_JPGDEC_BUFFER and CELL_GIFDEC_BUFFER.
Flipping / padding on .JPG and .GIF decoding

* Changes in cellJpgDec and cellGifDec come from cellPngDec.
RSX method naming modified

GCM commands (e.g. cellGcmSet*) are not the same as RSX methods (e.g.
NV4097_*). The name has to be changed.
Removed "Boot game and start" entry

There is already a setting on the menu (Settings > HLE > Always start
after boot) to do that. Make it active by default since disabling it is
only useful for debugging purposes.
